Abstract
The relative importance of inorganic carbon assimilation from the gas vs. aqueous phase by the floating duckweed Spirodela polyrrhiza was studied. It was found that carbon assimilation from the aqueous phase amounted only up to 5% of that from the air. No direct effect of pH on this process was detected. The experimental technique and the results are discussed with respect to those of previous studies, and possible sources of error are pointed out.
